Description

Technical Field

[0001] The present application relates to a water-cooling plate manufacturing device, in particular to a water-cooling plate high-frequency welding machine. Background Art

[0002] The description in this section provides only background information related to the present disclosure and does not constitute prior art. The water-cooling plate is a crucial component of the liquid cooling system in battery packs. It primarily consists of a plate, a sealing plate, and current collectors located at each end of the plate. Traditionally, manual welding is used to connect the plate and current collectors. This method is labor-intensive, inefficient, and unable to meet industrial production requirements, resulting in poor weld quality. Summary of the Invention

[0003] In view of this, the present application provides a water-cooling plate high-frequency welding machine, which can improve the welding efficiency and welding quality of the water-cooling plate.

[0004] In order to achieve the above objectives, this application is implemented through the following technical solutions:

There are more than one clamping assemblies and they are arranged between the product placement base and the pressing assembly. The clamping assembly includes a pneumatic clamp fixedly mounted on the bracket. The pneumatic clamp has two fingers that can open and close left and right, and is used to clamp the water-cooling plate from the left and right sides; the welding mechanism includes a high-frequency device and a welding wire ring fixedly arranged on the high-frequency device. The welding wire ring is located between the product placement base and the clamping assembly, and is sleeved on the outer periphery of the water-cooling plate. The high-frequency device can generate a high-frequency magnetic field on the welding wire ring, thereby heating the preset area of the water-cooling plate.

[0006] The above-mentioned high-frequency welding machine for water-cooled plates of the present application positions the water-cooled plates through a positioning mechanism, wherein the lower end of the water-cooled plates is placed on the product placement base, the downward pressure cylinder presses the water-cooled plates, and the pneumatic clamps clamp the left and right sides of the water-cooled plates in the middle position, thereby positioning and placing the water-cooled plates. A high-frequency magnetic field is generated by the welding wire ring, thereby heating the connection between the plate body and the current collector of the water-cooled plates, thereby melting the welding ring preset on the plate body and welding the plate body and the current collector together. Compared with manual welding, the welding efficiency is high and the welding quality is good.

[0007] In some embodiments, the welding mechanism also includes a welding guide rail and a welding cylinder, the welding guide rail extends along the front-to-back direction and is fixedly mounted on the machine platform, the high-frequency device is slidably connected to the welding guide rail, and the welding cylinder is used to drive the high-frequency device to telescopically move in the front-to-back direction; the rear end hollow area of the welding wire ring is a clearance area, the front end hollow area and the rear end hollow area are symmetrically arranged, the middle hollow area is a heating area, and the width of the middle hollow area is narrower than the width of the rear end hollow area. When the high-frequency device retracts, the clearance area of the welding wire ring is directly above the product placement base, and the lower end of the water-cooling plate can be placed on the product placement base through the clearance area. When the high-frequency device is extended, the heating area of the welding wire ring moves directly above the product placement base and is placed outside the water-cooling plate.

[0008] The wire loop's clearance zone is wide, facilitating placement of the current collector at the bottom of the water-cooling plate on the product's base. The heating zone is narrower. When the wire loop is extended, the heating zone moves to the junction between the plate and the current collector, applying heat at that location. The wire loop's front and rear ends are symmetrical, ensuring a more uniform magnetic field and achieving better heating results.

[0010] In some embodiments, a push rod is fixedly provided on the bracket for supporting the front side of the water-cooling plate. The push rod is used to support the front side of the plate body and reduce the shaking of the water-cooling plate.

[0011] In some embodiments, an infrared thermal sensing device for detecting the temperature of the heating area is also fixedly mounted on the bracket.

[0012] In some embodiments, an xy movable platform is further provided at the bottom of the product placement base for fine-tuning the product placement base in the left-right and front-back directions. This fine-tuning is to facilitate adjustment of the position of the product placement base.

[0020] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings. The terms used in the implementation methods of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0021] See Figures 1 to 4The embodiment of the present application provides a water-cooled plate high-frequency welding machine, comprising a machine platform 1, a positioning mechanism 2 mounted on the machine platform 1 for vertically positioning and placing a water-cooled plate 5, and a welding mechanism 3 mounted on the machine platform 1 and located in front of the positioning mechanism 2; the positioning mechanism 2 comprises a product placement base 21 fixedly mounted on the machine platform 1, a bracket 24 fixedly arranged on the machine platform 1, and a pressing assembly 22 and a clamping assembly 23 fixedly mounted on the bracket 24; the lower end of the water-cooled plate 5 is placed on the product placement base 21, the pressing assembly 22 comprises a pressing cylinder 221 fixedly mounted on the bracket 24 and located above the product placement base 21, and a pressing block 2 fixedly arranged on the piston rod of the pressing cylinder 221 22. The pressing assembly 22 is used to press the upper end of the water-cooling plate 5. There are more than one clamping assemblies 23 and they are arranged between the product placement base 21 and the pressing assembly 22. The clamping assembly 23 includes a pneumatic clamp 231 fixedly mounted on the bracket 24. The pneumatic clamp 231 has two fingers 232 that can open and close left and right, and is used to clamp the water-cooling plate 5 from the left and right sides; the welding mechanism 3 includes a high-frequency device 31 and a welding wire ring 32 fixedly arranged on the high-frequency device 31. The welding wire ring 32 is located between the product placement base 21 and the clamping assembly 23, and is placed on the outer periphery of the water-cooling plate 5. The high-frequency device 31 can generate a high-frequency magnetic field on the welding wire ring 32, thereby heating the preset area of the water-cooling plate 5.

[0022] This high-frequency welding machine positions the water-cooled plate 5 using a positioning mechanism 2. The lower end of the water-cooled plate 5 is placed on the product placement base 21. The downward pressure cylinder 221 compresses the water-cooled plate 5, and the pneumatic clamps 231 clamp the left and right sides of the water-cooled plate 5 in the middle position, thereby positioning the water-cooled plate 5. The welding wire ring 32 generates a high-frequency magnetic field, which heats the connection between the plate body 51 and the current collector 52 of the water-cooled plate 5, thereby melting the welding ring pre-set on the water plate body 51 and welding the plate body 51 and the current collector 52 together. Compared with manual welding, the welding efficiency is high and the welding quality is good.

[0023] The welding mechanism 3 also includes a welding guide rail 33 and a welding cylinder 34. The welding guide rail 33 extends along the front-to-back direction and is fixedly mounted on the machine platform 1. The high-frequency device 31 is slidably connected to the welding guide rail 33. The welding cylinder 34 is used to drive the high-frequency device 31 to extend and retract in the front-to-back direction; the rear end hollow area of the welding wire ring 32 is a clearance area 321, the front end hollow area 323 is symmetrically arranged with the rear end hollow area, and the middle hollow area is a heating area 322. The width of the middle hollow area is narrower than that of the rear end hollow area. When the high-frequency device 31 retracts, the clearance area 321 of the welding wire ring 32 is directly above the product placement base 21, and the lower end of the water-cooling plate 5 can be placed on the product placement base 21 through the clearance area 321. When the high-frequency device 31 is extended, the heating area 322 of the welding wire ring 32 moves to directly above the product placement base 21 and is placed outside the water-cooling plate 5.

[0024] The wide clearance area 321 of the wire ring 32 facilitates placement of the current collector 52 at the lower end of the water-cooling plate 5 on the product placement base 21, reducing the possibility of collision between the product and the wire ring 32. The narrow heating area 322 moves to the junction of the plate 51 and the current collector 52 when the wire ring 32 is extended, applying heat at the corresponding location. The front and rear ends of the wire ring 32 are relatively symmetrical, ensuring a more uniform magnetic field generated by the wire ring 32, resulting in a more effective heating effect.

[0025] The high-frequency device 31 includes a base plate 311 slidably connected to a welding rail 33, a second rail 312 fixedly mounted on the base plate 311 and extending in the left-right direction, a housing structure 313 slidably connected to the second rail 312, and a threaded push rod assembly 314 for driving the housing structure 313 for fine-tuning in the left-right direction. The welding cylinder 34 is connected to the base plate 311. The fine-tuning function of the high-frequency device 311 in the left-right direction facilitates installation and commissioning.

[0026] The bracket 24 is also fixedly provided with a push rod 233 for supporting the front side of the water-cooling plate 5. The push rod 233 is for supporting the front side of the plate body 51 to reduce the shaking of the water-cooling plate 5.

[0027] An infrared heat sensing device 4 for detecting the temperature of the heating area 322 is also fixedly mounted on the bracket 24 .

[0028] The bottom of the product placement base 21 is also provided with an xy moving platform 211 for fine-tuning the product placement base 21 in the left and right and front and back directions. The fine-tuning is to facilitate the adjustment of the position of the product placement base 21.

[0029] The following briefly describes the working process and usage of the water-cooled plate high-frequency welding machine in the above embodiment:

[0030] When assembling the water-cooled plate 5, it is necessary to first put the welding ring and the current collector 52 on the plate body 51. When using the high-frequency welding machine, the lower end of the water-cooled plate 5 is inserted into the welding wire ring 32 and placed on the product placement base 21, and the plate body 51 is leaned against the top rod 233. The equipment is started, and the cylinder 221 is pressed down to press the upper end of the water-cooled plate 5. The pneumatic clamps 231 clamp the left and right sides of the plate body 51 to position the water-cooled plate 5. Finally, the welding cylinder 34 pushes the welding wire ring 32 out, and the heating zone 322 moves into place, heating the corresponding position to melt the welding ring on the plate body 51, and weld the plate body 51 and the current collector 52 together. Then, the components are reset and the water-cooled plate 5 is taken out.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, rather than to limit them. Although the embodiments of the present application have been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
